We divide 68805518 by 509
Our goal is to divide 68805518 by 509.

Going ahead to step 1:
If we divide 6 by 509, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 509

Step 2:
509 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 509

Going ahead to step 3:
509 goes into 688 1 times with a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 509 from 688 leaves us with 179.
Fetch the next digit (0) from the dividend, attach it to 179 and continue: 1790 / 509

Step 4:
509 can be fit into 1790 3 times, resulting in a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1527 away from 1790, we end up with 263.
Append the next digit (5) from the dividend to 263 and continue with: 2635 / 509

Moving on to step 5:
The number 509 fits into 2635 5 times, leaving a remainder of 90.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 2545 from 2635 leaves us with 90.
Append the next digit (5) from the dividend to 90 and continue with: 905 / 509

Advancing to step 6:
The number 509 fits into 905 1 times, leaving a remainder of 396.
The next digit of our result is 1. 
Result so far: 1351.0
Subtracting 509 from 905 leaves us with 396.
Grab the next digit (1) from the dividend, add it to 396, then carry on: 3961 / 509

Advancing to step 7:
509 goes into 3961 7 times with a remainder of 398.
Use 7 as the next digit of our solution. 
Result so far: 13517.0
Subtract 3563 from 3961 to get 398.
Fetch the next digit (8) from the dividend, attach it to 398 and continue: 3988 / 509

Let's proceed to step 8:
509 can be fit into 3988 7 times, resulting in a remainder of 425.
The next digit of our result is 7. 
Result so far: 135177.0
Deduct 3563 from 3988 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 9:
If we divide 4250 by 509, we get 8 and a remainder of 178.
The number 8 becomes the next digit in our result. 
Result so far: 135177.8
If we take 4072 away from 4250, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
509 goes into 1780 3 times with a remainder of 253.
Put 3 as the next digit of the answer. 
Result so far: 135177.83
Subtract 1527 from 1780 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 11:
509 goes into 2530 4 times with a remainder of 494.
The next digit of our result is 4. 
Result so far: 135177.834
If we take 2036 away from 2530, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 12:
The number 509 fits into 4940 9 times, leaving a remainder of 359.
The number 9 becomes the next digit in our result. 
Result so far: 135177.8349
The remainder is 359 after subtracting 4581 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Going ahead to step 13:
509 goes into 3590 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 135177.83497
If we take 3563 away from 3590, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
509 can be fit into 270 0 times, resulting in a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 135177.83497
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 15:
When dividing 2700 by 509, we get 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 135177.8349705
The remainder is 155 after subtracting 2545 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 16:
1550 divided by 509 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 135177.83497053
If we subtract 1527 from 1550, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 135177.83497053, with a leftover of 2.3e-08.
